Well unfortunately the saga continues.  I've been putting miles on the bike, a couple hundred probably, and a few times that battery monitor showed red (no charge).  I figured it wasn't working right since it showed amber (warning) when I measured 14.5v so I ignored it, but today I discovered that the bike quits charging at lower RPM's when hot.  When I got home from work I found that hot idle charging is 13.1v, up to about 13.9 hot at 2,500 rpm.  When the bike cools off the charging is better.  I swapped a stock R/R on and no change.  I also checked the stator and I do not have continuity to ground even when hot, and I have 0.4-0.5 ohms between the legs whether hot or cold.  WTF?
